TYPE-=WRITING MACHINE.

SPECIFICATION" forming part of Letters Patent No, 312,981, datedFebruary 24, 1885.

Application filed December 26. 1853.

T0 aZZ whom it may concern.-

Be it known that I, DIANLY G. DODGE, a citizen of the United States ofAmerica, residing at Charlotte, .in the county of Eaton and State ofMichigan, have invented certain new and useful Improvements inType-Writing Machines, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention pertains to improvements in type-writing machines, havingfor its object to effect the operation of writing or printing withfacility and without the tapping of keys, while it is adapted also forwriting or printing in blank-books, for which type-writers, as usuallyconstructed, are not available; and the invention consists of thecombination and arrangement of parts, substantially as hereinafter fullyset forth and claimed.

In the accompanying drawings, Figure 1 is a plan view of my type-writer.Fig. 2 is a horizontal section on line as 00. Fig. 8 is a verticalsection of the type-wheel carriage. Fig. 4 is a bottom plan view of thesame. Fig. 5 is a view of the handle inverted. Fig. 6 is a longitudinalsect-ion of one of the parts detached. Fig. 7 is a vertical sectionalVlO \V of one of the types and its adj unctive parts. Fig. 8 is a detailview. Fig. 9 is avertical'sectional view wit-h parts broken away. Fig.10 is a longitudinal sectional view of my invention on the line y y.

Inthe organization of my invention I construct a framecomposed,preferably,of two end bars, A A,with downwardly bent orextended ends fastened to longitudinal base-bars A,se cured horizontallyupon inwardly-projecting horizontal plateextensions c c of said endbars, A A, thereby allowing the suspension of the printing or typecarriage between said side or base bars. To the front end of this frameis suitably connected the handle B, and to and between the two endpieces, 0 and G", of said frame are screwed or otherwise fastened twospaced-apart bars, I) b, to the upper and lower sides of which arescrewed metal plates 0 0, having slots (1 d,and which are rounded at oneend and partly so at the other, and fit into coincident recesses formedin the end bars.

At one end of the two spaced-apart bars I) b is an end piece 0 to whichis secured one (Modem of the end bars, A A. Said end piece (3 has anopening in its center wherein the wheel I is held in position.

Screwed or otherwise fastened to the sides of the bars I) I) aremetallic plates 0 0, having slots 0 0 extending nearly from end to endthereof.

D is the type-wheel carriage, composed, preferably, (although capable ofvariation in structure) of a disk or dial, D having lat oral anddownwardly bent or flanged exten sion D, fully clearing the twospaced-apart bars 2) b. One of the downwardly-bent or flanged extensionsD is passed in under the type-wheel carriage D, and rigidly connected tothe other downwardly-bent or flanged eX- tension D at a, thus formingthe lower bar or plate, D.

To the under side of the top plate D of the carriage D, one beingarranged on each side of and closely to the two spaced-apart bars 6b,are bolted or otherwise secured downwardly projecting right angledplates or brackets e, the inner face ends of which pro ject into theslots 0 c to effect the proper guiding of the carriage upon thebed-bars.

In one arm D and extending a short distance inward and through thetransverse bottom-connecting-plate,D",is also aslot, f, through whichthe required or depressed type is caused to project and impart itsimpression to the surface of the paper designed to receive suchimpression in effecting the printing or writing operation.

Through the longitudinal slots (1 d of the plates 0 0 passes the shaftE, bearing at its lower end centrally in the type-wheel D of thecarriage D, while above said type-wheel D it passes through the disk ordial D andis provided above the dial with a pointer, g, and at its upperend with a lever, 9, having aknob, g, at its outer end. The knobbedlever is capable of being moved upwardly and returned to its originalposition to permit the adjustment of other hereinaftendescribed parts inposition.

Articulated to an arm or between two disks, h, ofa bracket, 0 suitablysecured to extension D of the carriage D is a ring-lever, F, saidconnection being effected by an arm, h, fixed thereto, said latter armhaving a perforated disk, h, at its outer end sandwiched between the twodisks h. Although this may be the preferable way of connecting thering-lever F, any other convenient means for the purpose may be adopted.Diametrically opposite the arm h said ring-lever F is provided with asecond arm, h", which, (while the arm h rests on aspring, i, secured tothe dial D rests on a spring plunger or pin, G, recessed or notched tomore effectually hold said arm h thereon, and adapted to have movementin an aperture in the disk or dial D and to come into con tact with acoincident type head or extension, presently referred to, when force isapplied to the ring-lever. 'The plunger is elevated by its spring whenpressure is removed.

Disposed in a circle near the outer edge or margin of the type-wheel D,and so as to 00- cupy a coincident series of apertures or holes in saidtypewheel, are a series of types, H, composed of the letters of thealphabet, punctuation marks, figures, or other characters which aredesigned to effect the printing or writing.

Secured to the type-wheel D and arranged in a circle adjacent to thetypes H, are a series of vertical rods or studs, H, encircled by spiralsprings Hfiwhich act from-the type-wheel D against'perforatedrectangular extensions H at the upper ends of the type-stems,through'which projections the studs H extend, as

shown in Figs. 3 and 7. The upper ends of the studs H are provided withheads or enlargements which engage with the upper sides of therectangular extensions H of the types H, and arrest their upwardmovement caused by the action of the spiral springs surrounding thestuds H for the purpose of effecting the retraction of the type afterthe downward motion necessary to be given them for producing contact ofthe same with the material to be printed. The studs H by reason ofpassing through the rectangular extensions H at the upper ends of thetype-stems, operate to hold them in correct perpendicular positions andthereby bring the type-faces squarely against the paper to be printed,thus securing full impressions of the same.

Between the slotted plates 0 C is arranged an endless chain belt, I,passing over wheels I 1 the wheel I beingv disposed in one end betweenthe two plates 0 O, with its periphery contiguous to the curvature insaid end, and the wheel l located in the opening in the end piece 0 withits periphery adjacent to the curvature in that end, before described.The chain is thus guided and retained in position on the pulleys orwheels. The shaft E passes through an oblong square block or sleeve, L,within the box or case formed by the slotted plates 0 0, side bars, I)b, and end bars, 0 C The sleeve L is provided at one side with a groove,L, having a tooth, L which projects through the contiguous link of thechain I, as

shown in Fig. 2. The tooth L is so formed that it will be engaged by thechain I when it moves in one direction, and be cleared of the chain I bymeans of a lever, K, when it moves in an opposite direction, as will behereinafter more fully described. When the chain moves and engages withthe tooth L", the type-carriage is moved in a forward direction. Theside bar, I), is sufficiently extended inwardly, as indicated by thedotted lines in Fig. 1, to engage with the side of the oblong sleeve orblock L, and thus hold it in line with the chain I, the inner edge orside of the bar I) being rabbeted to allow the chain I to pass freely,all which is fully shown-in Fig. 3.

Upon the wheel 1 at the handle end of the maehine,is formed or connecteda ratchet, 1 with which engages a dog or pawl, J, projecting througha'slot, j, in that end of the box or case formed by end pieces, 0 G andplates 0 O, and pivoted to a thumb-lever, J, pivoted upon the lower sideof the handle 13, and capable of convenient manipulation by the thumb ofthe left-hand, while the type-wheel is being operated by the right-hand.This pawl or dog.

is held in its proper position by a spring, j, in contact with thethumb-lever J, (see Fig.

5,) secured to the inclosingcase, so as to partly cover the slotj, andbear on the dog or pawl when under pressure. The thumb-lever J is alsoheld in position as against too great a rearward movement by means of astop, j, and is moved to manipulate the dog or pawl, which acts topropel one of the chain-belt wheels, when the chain-belt wheel will bedriven and the carriage be moved longitudinally along its support,intermediate mechanism, presently described, assisting to accomplishthis end.

K is a lever, pivoted to the upper side of the dial D", next to thehandle end of the machine, and arranged between the dial and box andparallel with the slot in the plate C, the forward end of said leverhaving a small upright handle, while its opposite end is bent downwardthrough said slot and thence to one side where it terminates in a tooth,k. By press- IlO- ing said tooth 7c of the lever K against said chain,it will throw the chain I out of engage ment with the tooth L of theblock L, and allow the type-wheel carriage to be returned to any desiredpoint over which it has already been passed.

The block L is arranged to slide in ways formed between the plates 0 andG and the two spaced-apart bars I) and b, and to permit the type-wheelshaft to pass through it and through itself. In the center of one sideis a groove for the carriageoperating chain to pass through, thusadmitting it to slide with the carriage. In the forward end of thisblock is a recess, is, within which the inner toothed end ofthe lever Kworks or is capable ofhaving movement as it is projected into or againstand contact with the passing type of the type-wheel to cause therotation of the pads, and the propor application of the ink to thetypes. The bottom bar of the carriage may be semi-circularly recessed oneach side to allow, the closer arrangement to each other of the inkingpads or disks, while the latter, together with their connecting bar, arereadily removable by means of the above arrangement, to enable there-inking or-resupplyiug with ink of the pads. With this construction ofdevices, it will be seen that with the tooth L engaging the chain I, thetype-wheel carriage will,when subjected to the action of the parts, asabove described, be moved along its support at intervals occurring, asmay be regulated by the action of the thumb on the lever J, while by theturning of the type-wheel shaft E, by the action of the right hand uponits handle, and the depression of the handle, the process of writing orprinting will take place.

Preparatory to the writing or printing operation, the carriage is movedto the left or handle end of the supporting case of frame by slightlymoving the lever K in the direction of the arrow W thus causing thedisengagement of the chain I with the tooth L of the block L, whichallows the carriage to bemovcd toward the handle end of the machinewithout operating the chain and its wheels, which are prevented fromhaving a reverse movement by means of the pawl J. The handle of thetype-wheel shaft is now grasped and turned (the chain having again beenbrought into engagement with thetooth L of the block L) until thepointer on said shaft points to the de sired specific letter or type onthe dial D (which is designed to be correspondingly lettered or markedwith the type in the wheel,) when, by pressing downward upon the handle,the plunger will be forced upon and de press the corresponding letter ormark of the wheel-type, so as to make its impression on the surface ofthe paper upon which it is designed to print or write. The thumb'lever Jis now operated so as to cause its pawl or dog to actuate theratchet-wheel of one of the chain or belt operating wheels,whichwilldrive said chain and effect the movement of the carriage therequired distance or interval of making the next type-impression, whichoperation of moving the type wheel and depressing the lype,effectingtheprinting 0peration,and mov ing the wheel-carriage at intervals throughout the operation, will be continued until the required amount ofprinting or writing has been accomplished.

Having thus fully described my invention, what I claim and desire tosecure by Letters Patent, isp 1. In a type-writing machine, thecombination of the typewheel, and the type-wheel carriage D, having diskor dial D said disk or dial having lateral and downwardly-bent orflanged extensions D", one forming the lower bar, D, having slot f forpassage of the type when depressed, with the central vertical rotatingshaft, E, having pointer 91 and lever 9, constructed substantially asdescribed, and arranged to operate as specified, and for the purpose setforth.
